JOURNAL-LUBRICATING DEVICE.

SPECIFICATION forming part of Letters Patent No. 434,983, dated August26, 1890.

7 Application filed June '7, 1890. Serial No. 854,597. (No model.)

J r., of Marietta,in the countyof Cobb and State of Georgia, haveinvented certain new and useful Improvements inCar-Axle-Journal-Lubricating Devices; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, and to the letters of referencemarked thereon, which form part of this specification, in which Figure 1is a transverse vertical sectional view through a journal-box of arailway-car truck, showing my improved lubricating devices. Fig. 2 is alongitudinal sectional View through the same. 1 This invention is animprovement in lubricating devices for thej ournalsof car-axles, &c.,and comprises an improved oil-cup and a supplying-roller; and theinvention consists in the novel construction and combination of partshereinafter clearly described, and concisely stated in the claims.

Referring to the drawings by letter, A designates the car-axle journal,B the ordinary journal-box, and C the journal-brass interposed betweenthe journal and top of box.

D designates the oil-cup, which is placed within the journal-box belowthe journal, its sides rising above the lower periphery of the journal,and its end walls are recessed to permit the journal to lie partly insaid cup. The lower portion of the cup is reduced in size to form ashoulder d, extending horizontally around it. E designates aholding-frame for said cup, adapted to be slipped in the bottom of thejournal-box and fastened therein, and in this frame the cup is placed,its contracted lower portion fitting easily within the frame, and a pairof flat semi-elliptic springs e e are arranged horizontally in the frameand up holdthe cup, as indicated. The cup D has a central sink ordepression (1 in the bottom to accommodate a lubricating-roller F, whichis placed in the cup, and is mounted in journals formed on cross-piecesf f, fixed to semielliptic springs G G, that lie longitudinally of thecup and form. with the pieces f f, a rectangular spring supporting framefor the roller. The springs G G are kept in position within the cup bymeans of lugs g g, formed on the bottom of the cup, as indicated. Thesprings e e uphold the cup and hold its end walls in easy contact withthe lower portion of the journal to prevent escape of oil, while springsG G uphold roller F and cause it to bear against the lower face of thejournal yieldingly.

H designates a cover for the cup, having bottom flanges h, which restupon shoulder d and sustain the cover within the cup and below the sidewalls thereof and below the journal. The top of the cover is conoaved tocorrespond with the convexity of the journal, and it also has a centralopening 6, through which or in which the upper portion of roller Fcontacts with the lower portion of the journal,-and this portion issurrounded by low upstanding flanges t, which are also dressed to fitneatly against the lower face of the journal. The cover may also beperforated, as at h, to permit oil collecting in the space betweenflanges I t" to escape back into the cup. A space is left between thesides of the cover and the side walls of the cup above shoulder d, andany oil collecting in such space can drain back into the cup through theloose joint between the flanges h and shoulder d, and the flange mighthave transverse shallow channels or grooves formed in them to facilitatethe backflow of oil.

J J designate wings or flanges, which may be secured to the inner sideof the journalbox or tothe side edges of the brass C, and may be formedof metal strips fastened to the sides of thebox or edges of the brassand depending therefrom,their lower edges entering the space between thejournal and the side walls of the cup. It will be observed that theroller isscarely more than one-third the length of the journal; but Ihave found in practical use that the best results are attained by shortrollers, as they supply enough oil to properly lubricate the journal anda long roller supplies over-much oil and creates waste. The oil carriedup by the roller is supplied to the journal, and any grit or thickportions of the oil are wiped off by either of the flanges z" and thrownback into the cup. Then flange I wipes or distributes the lubricant yetmore, and any oversupply wiped oif by this flange collects on top of thecover and vis no waste, and that the journal is wiped continually by theflanges, so that no grit is carried up between the journal and brass,and that all oil wiped off or thrown off the journal by centrifugalforce is returned to the cup to be utilized; also, that the contactsbetween the cup and cover are maintained by spring-supports and theroller is held in yielding contact therewith by springs. By dressingdown the edges of flanges z" the amount of oil or thickness of theoil-film supplied to the journal can be regulated. Again, it will benoticed that each portion of the lubricating device is readilyaccessible and detachable from the others, and the cup proper and itscover are so formed or shaped that they can be made by free casting orwithout cores, thus greatly reducing the cost of the device. In order toreadily supply lubricant to the cup, I propose to connect a pipebend Kto an opening in the outer end wall of the cup and connect a straightupstanding pipe-joint k to this bend. This will allow an attendant toreadily-supply oil to the box without waste. The joints between thecover and cup are such that they effectually prevent waste of oil bysplashing.

Having described my invention, what I claim as new, and desire to secureby Letters Patent thereon, is-

1. In a lubricating device for journals, the combination of a cup havingside walls extending above the bottom of the journal and aspring-supported roller in said cup impinging against the journal, witha cover fitted between and below the side walls of the cup and beneaththe journal and having wipingfianges and an opening over the roller,substantially as described.

2. In a lubricating device for car-axle jourbrass and conduct such oilback into the box,

substantially as specified. I

3. The combination of the cup having recessed walls, a horizontalshoulder and side walls that rise above the lower portion of thejournal, and a lubricating-roller therein, witha cover supported on saidshoulder below and within the side of the cup and conveXed to fitbeneath the journal, and having an opening above the roller and flangesaround said opening and at the top edges of the cover adapted to wipeoil from the journal, substantially as and for the purpose described.

4:. The combination of the cup having recessed end walls and upstandingside walls, substantially as described, and the oil-supplying pipeconnected thereto and the lubricating devices therein, with the coverfitted between the walls of said cup and having upstanding fiangesadapted to Wipe oil off the journal, all constructed and arranged tooperate substantially as described.

5. The herein-described lubricating device for car-axle journals,comprising abase-frame, a cup fitting on said frame and supported bysprings therein and havinga horizontal shoulder, recessed end walls andside walls that rise beside the journal, with a spring-supported rollerin said cup contacting with the journal, and a cover resting on theshoulder of the cup between its side walls and below the journal andhaving wiping-flanges on its upper surface, and the wings attached tothe side edges of the journal-brass or to the inner faces of the j onrnal-box for directing oil back into the cup, all substantially asspecified.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.
